No. Never. If you do that then the address is tainted and you
*cannot* legitimately use information as it as evidence that mail
sent to it was unwanted. You can still use it for quite a few
interesting things, but you can't use it as a spamtrap (unless
you want to spend another year rejecting everything).
I talked about this at some length about six and a half
years ago. It wasn't a new problem then.
